Standard Radio System Plan

Table of Contents

1. Intent

1.1 This Standard Radio System Plan (SRSP) states the minimum technical requirements for the efficient use of the frequency band 7125-7725 MHz by low, medium, and high-capacity (LC, MC and HC) digital point-to-point radio systems in the fixed service.

1.2 This SRSP is intended to be employed in the design and specification of radio systems and equipment and in the evaluation of technical applications for new radio facilities or modification to radio systems submitted in accordance with the current issue of RSP-113.

1.3 This SRSP specifies equipment characteristics relating to efficient spectrum usage only and is not to be regarded as a comprehensive specification for equipment design and/or selection.

2. General

2.1 This Standard replaces SRSP-307.1, Issue 4. Revision of this SRSP will be made as required.

2.2 Radio systems conforming to these technical requirements will be given priority in licensing over non-standard radio systems operating in this band.

2.3 The arrangements for non-standard systems are outlined in SP-Gen.

2.4 The Geographical Differences Policy (GDP) Guideline applies in this frequency band. More information on the GDP can be found in SP 1-20 GHz.Footnote 1

2.5 Modifications may be required to a radio system whenever harmful interferenceFootnote 2 is caused even when the system conforms to the requirements of this SRSP.

2.6 When potential conflict between radio systems cannot be resolved, Industry Canada should be advised. After consultation with the parties concerned, the Department will determine the necessary modifications and schedule of modifications to resolve the conflict.

2.7 The Department may require licensees and/or applicants to use receiver selectivity characteristics that provide rejection of harmful interference.

2.8 The use of a two-frequency plan is required. Where reasonable economic or technical justification is provided (e.g. where siting prevents adequate antenna discrimination), extra frequencies may be used to resolve the problem, subject to the provisions of Section 2.4.

Use of frequency diversity by systems serving telemetry, control and protection purposes is allowed. In these cases however, it should be recognized that space diversity techniques will be encouraged. In cases where route diversity is used it may be necessary to deviate from the preferred two-frequency plans, and such systems will receive the same degree of protection as the preferred system.

The use of frequency diversity and route diversity could be considered if economic or technical justification is provided. The applicant must provide all necessary particulars in the licence application together with the overall frequency plan proposed.

2.9 It should be noted that the fixed service shares this band with other services in accordance with the Canadian Table of Frequency Allocations.

4.3 Branching or Spur Route Channels

The frequencies assigned to a main route system should be reused on the branching or spur routes where possible. The siting of repeater stations should be planned with this requirement in mind, in order that sufficient antenna discrimination is obtained at the branch-off-angle.

4.4 Closed Loops

Systems must be designed so that any closed loop will consist of an even number of hops.

4.5 Assignment of Frequencies

In sub-plans I and II, new systems should use the highest available frequency pair that can be successfully coordinated.

4.6 Frequency Pairing for Systems Operating with Frequency Diversity

4.6.1 For frequency diversity, the channels of sub-plan I should be paired with the following channels of sub-plan II, in accordance with Section 4.5.

  1. For digital radio systems with RF channel bandwidths of greater than 20 MHz and less than or equal to 30 MHz: GO channels An/A4+n should be paired with RETURN channels An'/A4+n' where n = 1 to 4.
  2. For digital radio systems with RF channel bandwidths of greater than 10 MHz and less than or equal to 20 MHz: GO channels Bn/B7+n should be paired with RETURN channels Bn'/B7+n' where n = 1 to 6.
  3. For digital radio systems with RF channel bandwidths of greater than 7.5 MHz and less than or equal to 10 MHz: GO channels Cn/C15+n should be paired with RETURN channels Cn'/C15+n' where n = 1 to 12.

4.7 Spectral Efficiency

4.7.1 Medium and high-capacity digital systems submitted for licensing shall have a minimum spectral efficiency of 4.4 bit/s/Hz of the RF channel bandwidth on a single polarization.

4.7.2 Low-capacity digital systems submitted for licensing shall have a minimum spectral efficiency of 2.4 bit/s/Hz of the RF channel bandwidth on a single polarization.

4.8 Protection Channels

Single channel systems requiring protection must employ hot standby protection with the exception of systems used for telemetry, control and protection purposes which may employ frequency diversity protection.

5. Transmitter Characteristics

5.1 The transmitter power delivered to the antenna input per RF channel should not exceed the following limit for each bandwidth as shown in Table 1:

Table 1: Transmitter Characteristics
Bandwidth
(MHz)
Power Limit
watts (dBW)
30 10 10
20 10 10
10 10 10
7.5 7.5 8.8
5 5 7
2.5 5 7

5.2 An increase in transmitter power over the above specified limit may be permitted if technical justification is provided. In no event will the power delivered to the antenna input be permitted to exceed 20 watts (+13 dBW) per channel.

5.3 The centre frequency of the emission shall be maintained within ± 0.001% of the assigned frequency.

5.4 Emission Limits

5.4.1 In any 4 kHz band, the centre frequency of which is removed from the assigned frequency by more than 50% up to and including 250% of the authorized bandwidth, the mean power of emission shall be attenuated below the mean output power of the transmitter in accordance with the following equation:

A = 35 + 0.8 (P - 50) + 10 log10(B) (dB)

where:
A = attenuation (dB) below the mean output power level
P = percent removed from the carrier frequency
B = authorized bandwidth (MHz)

Note:
1. In no case shall the attenuation be less than 50 dB.
2. Attenuation greater than 80 dB or to an absolute power of less than -13 dBm/MHz is not necessary.

5.4.2 In any 1 MHz band, the centre frequency of which is removed from the assigned frequency by more than 250% of the authorized bandwidth, the mean power of emission shall be attenuated by 43 + 10 log10 (mean output power in watts) dB, or 80 dB, whichever is the lesser attenuation.

6. Antenna Characteristics

6.1 The co-polarized radiation pattern envelope in the horizontal plane of the antenna must remain within the envelope shown in Figure 2, for both vertical and horizontal polarizations.

6.2 The antenna shall have a minimum front-to-back ratio of 65 dB.

7. Maximum Equivalent Isotropically Radiated Power (e.i.r.p.)

The maximum e.i.r.p. from the antenna must not in any case exceed +55 dBW per RF channel.

Footnotes

Return to footnote reference 1 SP 1-20 GHz, January 1995, contains new spectrum utilization principles including the Geographical Differences Policy Guideline. This information will be incorporated into a revision of SP-Gen.

Return to footnote reference 2 For the purpose of this SRSP, "harmful interference" means interference which endangers the functioning of a radionavigation service or of other safety services or seriously degrades, obstructs, or repeatedly interrupts a radiocommunication service operating in accordance with regulations and technical requirements laid down by Industry Canada under the Radiocommunication Act.


Image Descriptions

Figure 1

Figure 1 Illustrates the frequency ranges covered by the two sub-plans. Sub-plan I comprises 7125-7250 MHz paired with 7300-7425 MHz. Sub-plan II comprises 7425-7575 MHz paired with 7575-7725 MHz

Figure 2

Figure 2 is a line graph that shows the antenna radiation pattern limits in dB down from the main lobe for azimuth separations from the main lobe between 0 and 180 degrees.

The y-axis measures antenna directivity in dB down from main lobe from -40 to 0. The x-axis plots azimuth in degrees from main lobe from 0 to 180. There is one plot line which ranges from -38 to 0 on the y-axis. Data points are also given in Table 4. Measured radiation pattern in the horizontal plane must be within these limits for vertical or horizontal polarizations.
